DOUBLING-FRAME.

SPECIFICATION forming part of Letters Patent No. 682,878, dated September 17, 1901-. Application filed April 3| 1897. Serial No. 6301523a (No models To all whom, t may concern,.-

Be it known that I, WALTER G. MORRISON, a citizen of the United States, and a resident of Willimantic, in the county of Windham and State ot' Connecticut, have invented certain new and useful Improvements in Doubling-Frames, of which the following is a full, clear, and exact description, whereby any one skilled in the art can make and use the same.

My invention relates to the class of machines used for doubling silk or like fiber; and the object of my invention is to increase, inv a given size of machine, the amount of work that may be done within a given time by so constructing and arranging the mechanism that the machine maybe run ata high rate of speed as compared with prior machines'of this class.

Referring to the drawings, Figure lis adetail view, in vertical section, through the frame of a machine, showing on the right side of the figure my invention as used in doubling the threads from bobbins vertically arranged and with the parts in operation and on the left of the figure the invention as applied to the doubling of threads drawn from bobbins horizontally arranged, but with the parts out of an operative position. Fig. 2 is a View in front elevation of a portion of a machine, illustrating my invention, the bobbins being horizontally arranged. Fig. 3 is a front View of the trip-lever, finger-lever, and guide and yoke on enlarged scale. Fig. 4 is a detail front view of the tension device appurtenant to a single set of bobbins on enlarged scale. Fig. 5 is a detail plan View of the spreader and its support on enlarged scale. Fig. 6 is a detail side view illustrating mechanism for holding unuseddrop-wires in an upright position. Fig. 7 is a detail view in front elevation, showing the drop-wire holder in its lowermost position and in dotted outline in its raised position. Fig. 8 is a detail top view of the guide and brake-rod support.

In the accompanying drawings the letter A denotes the standards of the frame, one of which is located at each end and any suitable number at intervals along the length of the frame. Braces A A2 extend between the standards of the frame in line in the vertical center thereof, the brace A' being located near the top and the brace A2 directly thereunder and at a point somewhat above the horizontal center of the standards. Brackets B are secured to guide-rail extensions A3, pro*- jecting laterally from the standards, the brackets containing guideways for the guiderail C. Drop-wire-frame extensions A4 project downward and laterally from the standards underneath the guide-rail extensions 6o and form supports for a rail D, to which drop-wire frames, to be hereinafter described, are attached. S preader-su pports are secured at suitable intervals along the side of the brace A at just suicient distance apart to avoid interference in their operation. Each spreader support has arms a, to which spreader-arms b are pivoted. The spreadersupport is adjustably secured tothe brace by means ot'abolt passing through aslot a' and 7o bears a stop engaging with the cross-piece a2, extending between the spreader-arms, to limit the downward movement of thespreader.

`A starting-rod support a3 from the spreadersupport has a hole therein, through which extends a starting-rod c. The spreader, including the spreader-arms and cross-pieces, ex-

tends forward trom the pivot, the spreaderarms b branching outward, as shown. In the outer ends of the spreader' arms -are 8o formed bearing-slots b2. The bottom walls of these bearing-slots are formed in a plane extending diagonally to a vertical line, so thatl `the spindle of the bobbin is supported partially by the bottom wall of the slot and does not bear with its full weight upon the friction drive-wheel E, from which it receives its rotation. The object of thus constructing the slot, the bottom wall ot' which partially supports the weight of the bobbin, is to avoid 9o breaking of the slender threads by the sudden starting of the bobbin in throwing the parts of thel machine into operation. It has been found by experiment that when the whole weight of the spindle and bobbin bears upon the friction drive-wheel the threads are ,snapped ott by the sudden starting of rotation Vof the bobbin in the operation of the machine. This same objection is found in machines known as drum-spoolers or drum-dou- Ioo blers, in which that 'part of the bobbin upon which thread is being wound comes in contact with the drive-wheel or with an intermediate roller, which in turn comes in contact with the driving means as to its body part. This is a serious objection in machines of this class, as the rate at which they can be operated is limited, and the capacity of the machine is consequently limited. In such a machine it has been found that the snapping ed the slender threads is almost sure to happen after a certain speed limit is reached. By my improvement the rate at which the machine can be run, and the consequent capacity of the machine, is materially increased and the above-enumerated faults present in prior machines reduced to a minimum. This has been accomplished by so arranging the spreader and the slots therein that v the spreader serves merely to carry the bobbin into position where its spindle will come into contact with the periphery of the friction drive-wheel, and the slots are so arranged as to inclination that the bobbin is supported with just sufficient weight on the friction drive-wheel to enable it to gain and maintain its relative rate of speed of rotation with respect to said drive-wheel. The spreader is pressed down to a fixed stop, against which it is firmly held during the entire winding operation, so that any movement of the bobbin during the winding may not be in the least interfered with by any movement of the spreader. The upper wall of the slot prevents the bobbin from jumping, which would cause the threads to be snapped when it again came suddenly into contact with the friction drive-wheel, thus increasing the pressure on `the drive-wheel and suddenly accelerating its movement. The slots are so arranged as to direction with reference to the rotative movement of the friction drive-wheel that the force exerted by said wheel is decreased the instant the bobbin begins to move away in its movement in the slot and is not increased, as would be the case should the bobbin in its initial movement under pressure of the drive-wheel move in an opposite direction from that of movement of the surface of the said drive-wheel or against the force exerted thereby. This construction insures the bearing of the bobbin upon the friction drivewheel with a pressure depending upon and controlled by the relative speeds of rotation of said drive-wheel and bobbin-that is, as the spreader is moved downward the bobbinspindle suddenly striking the rapidly-rotating drive-wheel begins to rotate at very slow speed, owing to the extremely' light contact of the bobbin-spindle with the drive-wheel and the ability of the former to instantly relieve itself of that pressure. The bobbin, however, slowly increases its momentum until the speed to be imparted thereto is attained. Any unevenness that may occur in the contact-surfaces of the parts will cause in this starting movement the bobbin to move quickly away from the friction drive-wheel, so that its movement will not be suddenly accelerated by said unevenness to a degree to cause the threads to snap. No weightwhatever of the spreader is borne by the bobbin, the latter being perfectly free and having practically unrestricted movement to accommodate itself to any ofthe varying conditions that may be imposed as the spindle comes in contact with the friction drive-wheel. The arrangement of the slot as described provides a wall that overlies the spindle and prevents the bobbin from bounding out of its bearing in its rotation at the high rate of speed at which it is run. The parts are so adjusted that the spindle of the bobbin shall not rest at the bottom of the slot.

A supporting-recess ha is located in the bottom wall of each of the bearing-slots near their upper ends for the purpose of supporting the bobbin in a position with the spindle out of contact with the friction drive-wheel in the operation of takin g up the broken threads and preventing the stop-pins b4 on the bobbinspindle from encountering a positive stop, to be hereinafter described, as it is necessary that the bobbin be allowed permissive rotation as the thread is drawn off in the operation of taking up the threads. The friction drive-wheels E are supported on a shaft E', mounted in bearings on the frame, and which extends lengthwise of the frame in position to allow the friction drive-wheels to make contact with the spindles of the bobbins when the latter are dropped in the swinging movement of the spreader. These friction drivewheels are so located along the shaft that a single wheel makes contact with the ends of two bobbin-spindles, a single bobbin receiving its rotary movement from the operation of two friction drive-wheels.

The starting-rod is held in an upright position by the starting-rod support as, and to the upper end of this starting-rod is secured a starting-knob c'. This starting-knob is secured to the starting-rod as by means of a set-screw, and its upper end is properly formed to be grasped or pressed upon by the hand to force the rod downward against the tension of a spring c2, borne on the rod,- this spring pressing against a collar c3, ad j ustably secured to the rod and a fixed part on the frame of the machine. A starting-lug c4 on the starting-knob c overlies'the cross-bar a2, extending between the spreader-arms. A lifting-lug c5 as the starting-lrod is forced upward encounters a cross-bar on and lifts the spreader to a distance sufficient to disengage the bobbin-spindle from the friction drive-wheel which rotates it. The lug c4 as the starting-rod is pushed downward encounters the spreader and holds it during the entire winding operation iirmly in position with the bobbin-spindle in contact with the friction drive-wheel, the spreader resting on its stop. Means for holding the starting-rod in its lowermost position will be hereinafter IOO IIO

described. A positive stop c consists of an arm adjustably secured on the starting-rod and containing 'on its outer end a hook located in position to encounter the stop-pins b4 on the bobbin-spindle when the startingrod is in its upward position. The object of this stop is to cause the bohbin to immediately cease its rotation upon the breaking of a thread in order that the broken part shall not be wound upon the bobbin in the continued rotation due to the rapid rate at which the bobbin is driven.

A hanger d is secured to the brace A2, a lug d' on the hanger engaging the forked end of a guide e, ad; ustably secured to the starting-lever at or near its lower end. The upper edge of the guide encounters a shoulder formed at the base of the lug d as the starting-lever is moved upward and determines the extent of upward movement of the rod, and the arms of the fork lying on opposite sides of the lug form a guide to prevent rotation of the rod in its bearings. The starting-rod projects through a hole in the foot cl2 on the hanger that forms a bearing for the lower end of the starting-rod and also the spring c2. The front end of the guide bears a cam-surface e', that in its upward movement acts on a catch f on the pendantf, pivoted at its upper end to the foot d2, and throws the lower end of the pendant outward. The cam-surface c is so located with reference to the pendant f that when the latter hangs in its normal position the catch f will engage the upper surface of the guide e when the starting-lever is pushed downward, thus holding the starting-lever in its normal lowerrnost position. A trip-lever g is pivoted to the pendant f near its center and so nearly balanced on its pivot as to be easily swung thereon. The rear end of the lever, however, is slightly heavier than the front end, so that the rear end normally hangs downward. A trip-shaft F is mounted in bearings on and extends lengthwise of the frame and bears trip-cams F', located adjacent to the inner end of each of the triplevers. When the rear end of the trip-lever is swung upward into contact with the stop f2 on the pendant, the cams F strike against the end of the lever, forcing it forward, disengaging the catch f from the starting-lever stop or guide and allowing the starting-rod c to be forced upward under the impulse of the spring c2, thus carrying the spreader upward.

A drop-wire frame h is secured to the dropwire-frame rail D, and in the lower part of the frame are pivoted drop-wires h', each wire having a foot h2 of sufficient weight to throw the upper end of the drop-wire backward on the pivot when not engaged by a thread and of a length to encounter a cross-bar on the trip-lever g. Aloop h3 is formed in the upper end of the drop-wire, through which a thread from the supply-bobhin passes, the tension on the thread in the doubling operation being sufficient to hold the upper end of the dropwire in a forward position. When for any reason athread breaks, the pull on the dropwire is released, and as it swings backward the foot h2, coming in contact with the forward end of the trip-lever g, tilts it, throwing the rear end upward into the path of movement of the cams F. This contact between the parts operates to stop the machine, as hereinbefore described.

A tension-support 7l is secured to the rail D, and on this support is secured a tension device i. This tension device consists of a curved surface to which is secured a plush pad, the whole being located in such position with relation to a tension-arm that the thread is in contact with the curved surface to an extent to provide a proper tension for the thread. On the support for the pad is also pivoted a swinging tension-arm Zt, the threads from the supply-bobbins passing up through the eyes k3 in front of the tension-rod 794 and behind the tension-arm lc and thence onto the pad. A spring 7c is secured to the tensionsupport and with its end bearing with considerable face against flat surfaces k2 on the tension-arm 7c. These surfaces are arranged, preferably, at right angles each to the other and in such position with regard to the arm that the pressure of the spring on said surfaces will hold the arm in an open or closed position. f

The tension device above described is more especially applicable with the su pply-bobbins arranged in an upright or vertical position, as shown on the right-hand side in the view in Fig. l. With the supply-bobbins arranged in a horizontal position, as shown on the lefthand side of the machine in the view in Fig. 1, the bobbins are caused to revolve on a supportingspindle,which provides sufficient tension for the thread; but in the breaking of the thread the bobbins continue to turn, owing to the high rate of speed at which the machine is run, and Wind the thread up in a reverse direction on the bobbins. In order to prevent such winding, I have provided an automatic brake device constructed as follows: A bobbin-rail Gis secured to the side parts of the frame, along which the bobbins are supported in series. A bobbin-frame Z is secured t0 the rail G in any suitable manner and is provided with bobbin supporting arms Z', in which are located sockets for the reception of the inner ends of the spindles bearing the bobbins. These arms bearon their outer ends spring-stops Z2, secured to the arm and extending therefrom in a position to overlie the head of the bobbin. Rods m extend outward fromA the bobbin-frame and bear on their outer ends a support m for the outer ends of the bobbins, recesses, being located in this support with proper relation to the recesses for holding the opposite ends of the spindles to support the bobbins in a horizontal line. A brake-slide 'n is supported on the frame l in such manner as to have a vertical reci procation thereon brakes n being located on this slide in position to underlie the headV IOO IIO

of each of the bobbins. A pin n2 projects from the frame Z through a slot n3 in the slide, this slot and pin determining the extent of reciprocation of the slide. As the slide is moved upward the brake n comes in contact with the head of the bobbin, lifting the lat-ter upward until it presses against the spring-stop Z2.

The brake-slide is caused to operate on the breaking of a thread by mechanism as follows: The guide e is provided with a brakerod support o, having a guide-opening o', in which the end of the brake-rod p is loosely held, the lower end of the rod being secured to the brake-slide n. A finger-lever q is pivotally supported on the upper end of the brake-rod, the upper end of the lever bearing a hook g2, projecting through a lever-opening c2 in the brake-rod support o. A hook-stop o3 consists of a projection extending downward from the under side of the brake-rod support in line with the wall of the opening o2 and to an extent to continually lie in front of the hook q2. A weight Q3 is borne on the finger-lever in proper position to cause the upper end of the lever to be swung normally forward. It will be seen from this construction that as adrop-wire is swung backward by the breaking of a thread and the startingrod caused to move upward by the release of its trip the brake-rod is also carried upward, bringing the brake into action to stop the supply-bobbins from rotating, the hook q2 being normally in engagement with the upper surface of the brake-rod support o. In taking up the threads before the starting-rod has been pushed downward to start the receivingbobbin it is necessary that the brakes on the supply-bobbins shall be released in order to allow the threads to be drawn upward. This is accomplished by swinging the finger-lever backward until the hook q2 disengages from the upper surface of the support o, the weight of the rod and brake-slide carrying it downward to a distance sufficient to release the brake, but to keep the hooku in contact with the wall of the opening in the brake support or stop 03. After the threads have been taken up and the starting-rod pushed downward the finger-lever is caused to project through the lever-opening o2 and the hook to again engage the upper surface of the support.

In order to adapt the machine to the horizontal or verticall arrangement of the supplybobbins, a swinging bobbin-rail support r is located at intervals along each side of the machine, and a stop fr" is located on the frame of the machine to hold the support in a practically horizontal position. The bobbin-rail G is provided on one sidewith sockets s, in which the spindle of the bobbin is suported in a vertical position. When it is desired to support the bobbins horizontally,the rail-s upport r is swung upward to the position shown on the left of the frame of Fig. l of the drawings and the edge of the rail supported on a brace II, forming part of the machine. In this position the sockets s are located on the back side of the bobbin-rail and the framel on the front side. Pins t project .from the lower edge of the bobbin-rail into sockets in the brace H, and sockets on the upper edge of the rail are adapted to receive a swinging hook u, pivoted on the frame ofthe machine. This arrangement of the bobbin-rail enables the bobbins to be supported in a horizontal or vertical position simply by changing the p0- sition of the bobbin-rail from the horizontal to the vertical position, as shown on the right and left hand sides, respectively, of the frame in Fig. l of the drawings.

The description herein has been confined almost exclusively to the mechanism appurtenant to a single set of bobbins; but it is to be understood that the described mechanism may be duplicated to any desired extent along the frame of the machine, a complete set of devices usually being employed for a single set of bobbins; but in some instances the device operating in connection with two sets of bobbins, as in the case of the friction drivewheel for rotating the receiving-bobbins, is employed. A horizontal or vertical arrangement of the supply-bobbins on a single frame has been shown, it being common in the use of the machine to so loperate a single frame.

In Figs. 6 and 7 there is shown a device for holding the unused drop-wires in an upright position. This consists of a swinging frame having arms o, pivoted, preferably, to the outside of the drop-wire frame h at the upper end thereof. This frame has a cross-bar fu extending over the edge of the dropwire frame and downward, as shown in Fig. '7, in position to lie back of the unused drop-wires and just in front of the drop-wires in use, the unused drop-wires being located between this portion u and the rod Q12 on the drop-wire frame. The arms fu are of sufficient length and pivoted at the proper point, so that as IIO they are swung upward the upper ends of the drop-wires will swing underneath, as shown in dotted lines in Fig. '7 of the drawings.
